Abstract: Effect of time-sequence control on the coupling of strong magnetic field and shaped charge jet is analyzed based on the relevant depth of penetration (DOP) tests. Two kinds of magnets with different structures (Ⅰ-type andⅡ-type) are used in the experiments. The depth of penetration and the crater form, which is penetrated by the jet impacted by the magnetic field in different time-sequence, are measured and analyzed. Meanwhile, the effect of magnetic field under different time-sequence control on the stability of shaped charge jet is researched. The research results show that time-sequence control is one of the important influence factors. The major penetration ability of jet focuses on its front and middle parts. Its penetration ability is increased effectively if those parts are coupled with the magnetic field by improving the time-sequence control of the system. The penetration ability of jet produced by 56 mm shaped charge is increased from 1.7% to 32.8% under the effect of magnetic field generated by Ⅰ-type magnets, and the penetration ability is improved from 1.6% to 69.4% for Ⅱ-type magnets.
